The general object of my invention, like that of the above mentionedapplication, is to produce a locomotive air reservoir located betweenthe side frames of'the locomotive and formed of sufiicient crosssectional area to serve as a reinforcement of the framesand also forminga longitudinal member of the framing adapted to transmit longitudinalforces.

A more specific object of my invention is to simplify the castingoperation of a reservoir member which is cast integral with theunderframe. I also desire, in the preferred form of my invention, toform a section of a reservoir reinforcement member which in art, isintegral with the locomotive be or rame and to complete the member witha separately formed section applied thereto. In the preferred form ofmyinvention the side frames of the locomotive are united by a cylindricalreservoir member which either by itself, or in combination withco-operating members applied thereto, forms the backbone of the frameand serves to transmit the major portion of the vertical and lon'tudinal forces present in the frame.

In the construction illustrated in Figures 1 to 5, inclusive, the sideframes are indicated at 1 and are shown as includin pedestaljaws 2 andprovided at intervals wit equalizer crums 3 and brake hanger brackets 4.'The frames are united at their rear by a transverse member 6 whichalsoforms the front end of a cradle having sides 7. 'While I show thiscradle structure as formed integrally with frames 1, it will beunderstood that it may be separately formed and attached to the frames.

forward ends of the frames merge to form the front deck 8 and thisportion of the structure is provided with integral pads 9 for mountingthe brake cylinder 10.

Intermediate the side frames 1 and extending throughout a substantialportion of the length of the structure is a cylindrical member 11 havingopen ends and connected to the side frames by vertically spacedsubstantially horizontal webs 12 which are provided with substantialopenings 13, whereby the structure is lightened Preferably, member 11,webs 12 and side frames 1 are all formed integrally with each other,either by casting in a single unit or by the welding together into anautogenous whole arts which have been formed separately. 'Ihe structureis reinforced by upstanding ribs 14 and by shorter upstanding elements15 which also form brackets for mounting piping for conducting air,water and other fluids from one part of the locomotive to another. Belowmember 11 and merging therewith and with the pedestal jaws 2 are crossmembers or transoms 16. Suitable integral brackets 5 are provided atintervals for mounting the expansion plates 17 on which the boiler shell18 is carried.

Member 11 terminates at its ends in vertical flanges 19 and the endportions of the reservoir are formed by cup-shaped members 20 and 21,respectively, each having flanges 22 on its inner end adapted to bebolted to the corresponding flanges 19 of the central member 11 of thereservoir. Horizontal flanges 23 are provided on the outer ends ofmembers 20 and 21 and rest on the transverse members 6 and 8 of theframe.

In order that the members 20 and 21 may serve as reinforcements of theframe structure, I provide complementary lugs 25 and 26 on the frame andflange respectively and utilize wedges 27 to provide a thrust-resistingengagement between the lugs on the two parts. With this constructionvariations in the length and machining of members 11, 20 and 21 may beaccommodated and draft and buffing forces may be absorbed or transmittedby the reservoir structure, the same forming a backbone of cylindricalsection throughout that portion of the locomotive frame in which theeffective depth of the side frames is greatly reduced because of therecesses for the driver axle boxes.

The side frames 1 are braced by suitable transoms or cross bars 28extending below reservoir members 20 and 21 and having their upperelements depressed, as best shown in Figure 5, to clear the reservoir.End members 20 and 21 are provided with pipingbrackets 29 correspondingto brackets 15 on the central member 11.

In Figure 6 I indicate a modified form of wedging the reservoir endmember 30 to the frame member 31. In this construction, a single wedgeor key 32 is provided between 111 s 33 and 34.

igures 7, 8 and 9' illustrate a modification in which a cylindricalreservoir body member 35 is provided with integral brackets 36' forattachment to locomotive side frame members 37, and reservoir endmembers 38 are provided with similar brackets 39 for attachment to theside frames. Members 35 and 38 have abutting flanges 40 for attachmentto each other and each of these members is preferably provided withbrackets 41 for mounting piping. Members 38 also have expansion platebrackets 42 and member 35 has depending elements forming a transom 43having a flange 44 for connection to the pedestal jaw 37*. With theabove described structure, smaller units may be used and securedtogether by bolts, rivets or welding and, at the same time, the bracingof the side frame by cylindrical reinforcing member is effected.

Figures 10 and 11 illustrate another modification of the structure shownin Figures 1 to 5 in that the end members 45 applied to the open-endedcylindrical body 46 are relatively short and, in effect, comprise capsfor the central member and have no connection with the side frames 47,apart. from their connection to the body member 46. With thisconstruction, a relatively short reservoir is provided but the hollowcylindrical reinforcement of the spaced side frames is retained.

If desired, the frames may be connected to each other in any usualmanner at points spaced from the reservoir longitudinally of the frame.Figures 12 to 15 illustrate a construction 1n which the reservoir mainbody member 48 comprises a cylinder with flanged ends 49 to which caps50 are applied. Caps 50 include lateral extensions 51 secured to theside frames 52, preferably including expansion plate brackets .54 andbrake hanger lugs 55 and piping brackets 56.

A transom 53 may be located intermediate the ends of the reservoir forthe purpose of bracing the side frames but member 53 has no connectionwith the reservoir member 48 and does not extend over the top of thesame.

Figure 16 illustrates a modified form of connection between the mainreservoir member 57 and the end members 58. The latter is provided witha rib 59 spaced from its inner surface 60 and providing a shoulderedrecess adapted to receive the edge and adjacent portion of thecylindrical body member 57. Member 58 is welded to 57 at W.

In the construction illustrated in Figure 13, the reservoir is solocated relative to the pedestals that the end members 50 areintermediate the drivers and there is no occasion for providing members51 with the downward extensions for connection to the pedestal jaws suchas are provided on member 53 but it will be understood that if thelength of the reservoir is such as to bring the end members abreast ofpedestal jaws, it would 13 In the construction shown in Figure 18,

the transverse bars 63 are formed integrally with the side frames 64 andextend around the reservoir 65 which is made separately and placed inthe mold before pouring the frame.

Figure 19 illustrates a structure similar to that shown in Figure 17 butin which the upper (portion 66 of the transverse bars 67 is in g morcement for the same and also forming forme separately'from the lowerand main portion and is bolted or riveted thereto as indicated at 68.

Figure 20 illustrates a similar modification of the structure shown inFigure 18, the lower main portion 68 of the transverse bars being formedintegrally with the side frame 69, the upper portion 70 being formedseparately and secured to the lower portion and frame by bolts or rivetsat 71.

In each of the forms of my invention described above, the side framesare braced by a tubular member which also forms an air reservoir locatedbetween the frames. This construction avoids the location of reservoirson the exterior of the boiler shell and eliminates the material andlabor required for securing the reservoirs in their usual location. Thecenter of gravity of the locomotive is lowered and less material isrequired for the side frames in order to attain a given resistance toforces transmitted through the underframe.

Various other modifications in the details and arrangement of thereservoir parts may be made without departing from the spirit of myinvention and I contemplate the exclusive use of such variations as comewithin the scope of my claims.
